Can any one help … Re: argumentexception property cannot be found 13 Years Ago by valter I'm not sure about the managed unmanaged issue, it's just a dll I wrote myself witha few functions handling photos. Just tried externalexception in the dll itself? But it still has the same problem. Should I use the externale4xception in the calling routine, rather than the one I am calling. using (Image img = Image.FromFile(imagefileName)) I … Re: argumentexception property cannot be found 13 Years Ago by Momerath In the calling routine Re: argumentexception property cannot be found 13 Years Ago by valter Thanks, I have tried that but the program keeps stopping in the dll. The strange part is that if I step thru it will stop, and then go to the catch statement on the next step. But while it's running the program crashes. The routine works fine with most pictures, but as I said before I don't think the scanned image has that property. What I can't … Re: argumentexception property cannot be found 13 Years Ago by valter I finally solved it, albeit by a quick and dirty way. I am putting my solution here for anyone that has a similar problem. I researched and could not find a way to stop an exception being thrown in the try statement which stopped the code. I then thought maybe I can test for the condition that stops the code.

Thanks Re: ArgumentException Occurred: Parameter is not valid: 12 Years Ago by BoBok2002 [QUOTE=annette123;1642226]I will try it and let you know if it works. Thanks[/QUOTE] I had trouble using your code because it returned a bitmap instead of an image. If I used it then I would have to change the Camera class which was also coded to receive image files. I will still try it all the same. Thanks. Re: ArgumentException Occurred: Parameter is not valid: 12 Years Ago by Momerath ??? A bitmap is an image, it's derived from the Image class. Anywhere you use an Image, you can use a Bitmap. Re: ArgumentException Occurred: Parameter is not valid: 12 Years Ago by BoBok2002 [QUOTE=Momerath;1645947]???

I recommend against using "key" and "value" as your variable names, especially when you choose to use the following in one of your dictionaries: `this.… Re: morse to text dictionary - System.ArgumentException: An item with the same 9 Years Ago by JOLO528 I try your code.

Re: morse to text dictionary - System.ArgumentException: An item with the same 9 Years Ago by cgeier Encoding should match the encoding of the file you're using. Using more try-catch blocks (as shown above) will help you to troubleshoot and will cause little to no performance issues since you're using such a small dataset. Note: '7' and '(' have the same value above. You use the values as the keys for your second dictionary-latinka.
